Is your Huawei inverter no longer producing data? Let’s get that back for you with the Solar Analytica Huawei Inverter WiFi Reconnect Guide. The great news is that this is often only ever a minor issue. Chances are, the solar energy system is still producing power, you simply can’t see this information being logged anymore through the FusionSolar app.
The following guide is applicable for all Huawei wifi-enabled solar inverters, including the SUN2000L, SUN2000-L1, SUN2000-M0 and SUN2000-M1.
Ask yourself the following questions;
- Was there a blackout or a power outage recently?
- Has the modem been switched off for any reason recently?
- Have you recently changed your internet connection?
- Has the modem been changed or upgraded?
- Has the solar system been switched off recently?
- Has an electrician been working on the property?
If you answered yes to any of the above, then there is a high chance your Huawei inverter has disconnected from your WiFi network. In a nutshell, your inverter is now trying to communicate through an IP address which is no longer available from your modem.
It’s important you know the steps to reconnect any WiFi based device as IP addresses will continue to change over the systems lifetime. Here is how to get your Huawei inverter WiFi reconnected.
IMPORTANT: If your Huawei inverter has disconnected from your WiFi network, this will not affect your solar energy systems ability to produce energy. It will only prohibit communication to the Huawei FusionSolar cloud service that allows you the view your solar production information.
Requirements before initiating sequence.
- Physical access to your Huawei inverter.
- A WiFi-enabled device such as a smartphone or tablet.
- The Huawei FusionSolar app installed on your smartphone or tablet.
- Patience, the average reconnection time is 10mins.
Note: The easiest way to reconnect is by scanning the QR code at the bottom of the label on your Huawei inverter to connect to the inverter’s wifi once you have opened the FusionSolar app. If this is not an option on your inverter model, follow these 5 steps:
Step 1: Wireless access configuration.
Open the FusionSolar app on your smartphone or tablet device.
Select the WiFi tab in the top left-hand corner, then the second option Tap to go to system settings.
Select the WLAN Inverter tab at the top.
An image of your inverter will appear under the heading, select the inverter.
The Identity Authentication page will appear. Select the Installer tab from the account drop down menu and enter the password 00000a, then select Verify.
Step 2: Network Set-up.
Go to the Communication Configuration tab, then Router Connection Settings and enable the Connect to a wireless router function.
Press the WLAN arrow and a list of available WiFi networks will appear. Select your network from the list and then insert the password for your network.
Step 3. Enable DHCP.
Ensure that the DHCP (Dynamic Host Configuration Protocol) option is enabled and that the domain name is;
- au1.fusionsolar.huawei.com for SUN2000 single-phase inverters and SUN2000L-KTL inverters installed prior to December 2019.
- sg5.fusionsolar.huawei.com for all SUN2000-KTL-MO three-phase inverters and ALL inverter models installed from December 2019 onwards.
Note: From March 2020, the au1.fusionsolar.com domain will be migrated to the sg5.fusionsolar.huawei.com domain.
Step 4. Internet connection status.
Step 5. Check app.
Open your NetEco or FusionSolar app and your system should now resume displaying energy data.
By the end of this process, you’re probably thinking why isn’t there just a simple WPS button like many other WiFi-enabled appliances? We hear you. Unfortunately, many mainstream inverter manufacturers haven’t adopted such modern conveniences yet. Therefore, this method currently is the best, most secure method for Huawei inverters.
Take your Huawei inverter to the next level.
